CARLINE REENFORCEMENT AND LQAD-LIFTING ATTACHMENT.

In some railway freight cars the roof structure comprises carlines spanning the distance between the opposite side plates with metallic roof sheets spanning the distance between the adjacent carlines. These roof sheets are sometimes secured to .the carline. making what is known as a rigid allsteel roof. and sometimes positioned loosely between the carlines, making what is known a as a flexible all-steel roof. In such types of roofs the bottoms of the carlines aresubstantially flush with the bottoms of the roof sheets, thus obtaining a flat interior surface,

so that it is frequently impossible to secure a rope or book to the carline, or, in fact, to

any other part of the roof, therefore, it is diflicult and cumbersome to move heavy loads into, out of or around in the car. I

My invention resides in reenforcing all or some of the carlines of such an all-steel. car roof by means which also constitute a support for load lifting devices and comprises means for attachment of such device.

An object of the invention is to provide a pair of web plates to strengthen the carline and to provide a member which forms a splice plate to connect the web plates and form a unitary beam of the carline, web plates and memben which member alsohas means integral therewith for attaching load lifting devices.

The end plate is the end carline of a railway car for all intents and purposes of this invention, therefore, no distinction is made' in the claims herein.

Application filed January 14, 1927. Serial No. 161,093.

Inthe form illustrated the roof comprises roofsheets 2 which span the distance between the opposite side plates 3. and are secured thereto. These sheets have upstanding flanges 4 at their adjacent margins and an inverted U-shaped carline 5 covering and embracing the flanges adjacent the roof sheets. In order to strengthen any carline to which it is desired to attach a load lifting device I provide a pair of vertical web plates 7 positioned between the roof flanges and attached to the carline 5 on opposite sides of the center line of the car. These plates 7 must be relatively narrow adjacent the'side plate at 8 in order not to reduce the inside height of the car but they must be relatively wide adjacent the center of the car so as to project below the roof'sheets far enough to-accommodate the rivets 9 which secure them to a splice member. These vWeb plates are preferably made from a rectangular plate by cutting it diagonally, as shown in Fig. 4;. The web plates 7 -7' on the opposite sides of the center line of the car are connected by a splice member 10 which may be a fiat plate, but I prefer to make it of'a U-section 11, as shown particularly in Fig. 3. This splice member is provided with an aperture 12 throughwhich the hook or chain 0 a load lifting device may be passed, and

' in order to position this aperture as near the underside of the roof as possible, I prefer to clip 0a the corners of the web plates at 13 which also reduces the height of the splice,

thereby maintaining the maximum inside height ofthe car. V I

I prefer the U-shape splice member 11 because it reduces the number of rivets (9) required by putting them in double shear.

' Furthermore, it increases the bearing area of the bottom ofthe aperture 12' whichengages the rope or hook of the load lifting device, and, thirdly, the upper flanges. 15 of the U-shape splice prevents it from tearing out under 'stress,either in service or process of manufacture.

Figs. 5 and 6 show my invention applied to another roof wherein the walls 20 of the carline 21 are-spaced further apart and the roof sheet flanges 22 secured. to

the carline but not to each other. In these figures also I have shown a splice 23 formed by a rolled T section with its lower flanges 24 curved upwardly forming integral means for the attachment of hooks or ice tongs of a load lifting device. These lower flanges also increase thestrength of the'spli'ce. The splice member may be provided with an aperture Figs. 7 and 8-show m-y-invention applied.

to a flexible all steel roof wherein the roof sheets and: their.flangesfilitare spaced apart from the carlines 32 andcovered by a cap 33 usually secured to the carline. There is free movement between the roof sheets on opposite'sidesof the carline as wellas betweenth'e roofsheets and vthe cap'., In this construct-ion Ihave shown a splice'formed by twooppositely'disposed flatmembers 34 providedwith registering apertures 35.

It is'undersood that any ofth'e' splice members or means for attaching aloadlifting, device described herein :01: any construction similarthereto may be used with any of the. roofs shown herein or any similar roof'thereto;andistill come within the scope of this invention;

The pitch of the roof varies in different carsor the variation inthe depth of the carline may bedifferent, therefore, in some cases it may be that the beam (formed by the combination of the carline, web plates and splice plate) is relatively weak between the endof the splice and the side plate so in order to provide more strength between these points I provide a flange 40 at the lower margin of the web plate, which flange does not decrease the inside height'of the car. This flange may increase in width from adjacent the splice (4:1)toward'the side plate 3 in proportlon to its decrease in vertical width" so that it may be made from a rectangular plate.

My co-pending application No. 93,155,v filedMarch 8, 1926, shows a pair of'web plates used to reinforce a carline, but the invention covered by this application for patent is an improvement thereon, as the single member used to connect the opposite 'ly disposed web plates also provides integral means for attaching aload lifting device.
